Abstract

本发明实施例公开了一种无线通信方法及系统、全双工无线收发机，该方法包括将发射数字信号调制成第一射频信号后将第一射频信号输出给发射天线，之后在预先生成的控制信号的控制下对第一射频信号进行相位调整及幅值调整，并获取抵消信号，再将通过接收天线从无线空口接收到的第二射频信号与抵消信号进行自干扰抵消以生成自干扰抵消后的第三射频信号，最后将第三射频信号解调成接收数字信号。本发明实施例可以根据无线自干扰信道的信道特性对发射的射频信号进行相位及幅值调整以生成抵消信号，并使接收到的射频信号与抵消信号进行自干扰抵消，降低了全双工通信模式下发送的射频信号对接收的射频信号的干扰，提高了移动通信的可靠性。
